, SPINNING-MACHINE.

Specification of Letters Yatent.

Patented Oct. 1,1912.

Application filed December 1'7, 1910. Serial No. 597,829.

To all whom it may concern:

Be it known that I, FREDERICK S. OULVER, a citizen of the United States,residing at Taunton, in the county of Bristol and State ofMassachusetts, have invented a new and useful Improvement inSpinning-Machines, of which the following is a specification.

This invention relates to a certain new and useful improvement inspinning machines and relates more especially to means for lifting allof the guide eyes of the machine from the builder motion.

The object of the invention is to provide means of this type whereby allof the guide eyes of the spinning machine can be lifted in unison fromthe builder motion by an improved, simple and novel construction now tobe set forth.

A structural embodiment of the invention is illustrated in theaccompanying drawings, in which- Figure 1 is a fragmentary sideelevation with parts in section of the improved spinning machine. Fig. 2is a fragmentary perspective view showing the present inventionseparated from the machine proper, and Fig. 3 is a detail fragmentaryside elevation.

The spinning machine shown in the drawings includes the ring rail 5,bobbin 6, drawing rolls 7, and the thread 8 which is led through thethread eyes or pig tails 9 on the guide rail 10. The vertical operatingrods 11 are slidably supported in the bearings 12 which latter areadjustably secured to thedownwardly-extending arm 13 which is connectedto the spinning machine frame as by means of a bracket 14;, the latterbeing secured to the frame. It will be observed that the arm 13 isformed with a series of longitudinal slots 15, while each of thebearings 12 and the bracket 14 are formed with a longitudinal slot 16,the slot 16 being at right angles to the slots 15, and bolts 17 beingpassed through the registering portions of the slots to thereby allowthe arm 13 or the bearings 12 to be adjusted either in a horizontal orperpendicular direction for the purpose of properly positioning the armswith relation to the rods 11. Each of the rods 11 carries a collar 18adjustably secured thereto, and rigidly connected to each of the collars18 is one end of a metal or other strap 19, the opposite ends of therespective straps passing over and being secured to'sma'll pulleys 20carried on a horizontal shaft 21, the downward movement of the latterbeing terminated automatically by the engagement of the collar 18 withthe lower bearings 12. The shaft 21 extends the entire length of theframe and is supported in suitable bearings formed in the arms 13. Alarger pulley 22 is keyed to the shaft 21 and has a metal or other strap23 secured thereto, the strap passing over the pulley in the oppositedirection from the straps 19 and extending downwardly and being securedto a slidably adjustable block 24 carried by the builder motion lever25. The lever 25 is pivotally secured to the fitting 26 which is securedto the rocker shaft 27 and is provided with the outwardly extendingtongue 28 which is rigidly connected thereto. The arm 29 secured to therocker shaft 27 carries the usual weight 30 for counterbalancing theweight of the ring rail.

When the machine is running and the builder motion is, in consequence,in operation, the action of the rocker is in effect to bring the tongue28 in contact with the lever 25 at a predetermined time of adjustment,so that the lever 25 will move in unison with the rocker and will effectthe corresponding actuation of the shaft 21, which will be transmittedthrough the pulleys 20 and the straps 19 to the rods 11. As the parts,just described, are actuated, the shaft 21 will be given a rotaryreoiprocatory motion whereupon the thread guide rail. 10 will belikewise lifted and lowered so as to cause the guide eyes or pi tails 9to advance toward and recede from the tops or the bobbins. The operationjust described remains the same regardless of the number of operatingrods employed.

The connections between the rods 11 and the guide rail .10 may be of anyform desired and there may be any number of rods used, the numberemployed being wholly dependent upon the length of the frame.

Having thus described my invention, I claim as new and desire to secureby Letters Patent In a spinning machine, in combination with a framehaving a pair of superposed horizontal bearings, a vertical rod slidablein said bearings, an adjust-able collar on said rod disposed to directlyengage the top face of one of the bearings to limit the Copies of thispatent may be obtained for side of the shaft that is opposite to theside thereof on Which the first named strap extends, said straps havinga substantially 15 parallel relationship.

In testimony whereof I have signed my name to this specification in thepresence of tWo subscribing Witnesses.

FREDERICK SLOCUM GULVER.
